SBS 2008 external users can't access exchange in outlook 2010, owa works fine
Posted on 2013-01-08
I have had a search through here but nothing seems to help. We have an SBS 2008 running exchange. About a month ago we updated our SSL certificate to a UCC one from GoDaddy. Now our external users outside the internal network can't access emails in Outlook. The error constantly says 'This action can not be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action'
I have tried every solution I have come across but I cannot get it to work. The users can access the emails in OWA fine and also on their mobile devices just not in Outlook 2010.
